Product Description P/N: 1489-A1C100
Description
The Allen-Bradley 1489-A1C100 is a miniature circuit breaker designed to protect branch circuits and control wiring from overloads and short circuits. Rated at 10 amps and 277 VAC, this single-pole breaker provides dependable protection in industrial power distribution and automation panels. Its C-curve trip characteristic makes it suitable for circuits with moderate inrush currents, such as lighting, control loads, and auxiliary equipment. DIN-rail mounting allows for quick installation in compact or modular panel designs.

Information About 1489-A1C100
The 1489-A1C100 is part of the Allen-Bradley 1489 series of miniature circuit breakers engineered for IEC-style industrial control applications. This model features a 1-pole configuration, a 10 A thermal-magnetic trip mechanism, and a voltage rating of 277 VAC or 48 VDC. The breaker uses a C-curve profile, providing reliable protection for circuits where equipment startup may cause short-duration surge currents. Its compact design integrates easily into control cabinets, MCCs, and distribution assemblies using standard DIN-rail mounting. Although discontinued in 2014, the unit remains widely used as a replacement component in legacy installations due to its durable construction and consistent trip performance. It is suitable for applications such as lighting panels, HVAC controls, machine tooling, and general auxiliary circuits.
Key Features:
- Miniature Circuit Breaker: Compact form factor ideal for industrial control and panel applications.
- 10 A Rated Current: Provides branch-circuit protection for low- and medium-load circuits.
- 1-Pole Design: Suitable for single-phase AC or DC circuits.
- 277 VAC / 48 VDC Rating: Supports common industrial voltage levels.
- C-Curve Trip: Designed for circuits with moderate inrush or switching currents.
- Thermal-Magnetic Protection: Offers reliable overload and short-circuit response.
- DIN-Rail Mounting: Enables fast installation and modular configuration inside control panels.
- 50/60 Hz Operation: Compatible with both standard industrial frequency ranges.
- Legacy Component: Replacement part for discontinued Allen-Bradley 1489 series breakers.
- Durable Build: Engineered for long-term dependability in industrial environments.
- Versatile Use: Suitable for HVAC, lighting circuits, control cabinets, and auxiliary automation loads.
The 1489-A1C100 delivers the reliability and precision required for industrial power distribution and circuit protection applications.
